Pasty butt, are some breeds more susceptible?

[Raubkatze]

My first round of chicks ( now 11 weeks old, two EEs and two Australorps) never once had pasty butt. My second round of chicks are two more Australorps and three Speckled Sussex. The Speckled Sussex have all had pasty butt once each since I brought them home two days ago. I check them twice a day, so I've always caught it and cleaned it quickly. I'm feeding them the same brand of food they had at the feed store, Kalmback Chick Starter. They are on shavings and I'm swapping out their most used areas once a day. Is there anything else I can do to help them not keep getting this? Are some breeds just more suseptible to pasty butt?

To me it seems random. I've read temperature of the brooder can affect it, both too warm and too cool, but so far I haven't figured it out.

Having just cleaned 6 out of 15 bottoms on bantam Cochin I can say fuzzier butts collect more crud.

They have a brooder plate. They are in an unheated room this time around, the old summer kitchen, but it has windows on all sides that cause it to be like a greenhouse. It's consistently 20 degrees warmer in there than outside. It think it's been a toasty 75 in there most days despite it being in the 50s outside. Guess I'll just keep an extra special eye on them.
